Usage Information

You must globally configure prefix as an optional parameter. You can configure hostname, VRF Name, or a customized string as prefix. Colon ( : ) is not allowed in the customized string prefix configuration. If you try to configure the prefix value with colon ( : ), the following error appears: OS10(config)# % Error: Colon ( : ) is not supported

If the hostname is configured as a prefix, then the system hostname is used by default.

If the vrfname is configured as a prefix and the client connected interface is not configured in any non-default VRF, then default is used as prefix vrfname.

NOTE: This command is restricted to the sysadmin and netadmin user roles.
